A USB-SATA conversion circuit board of a memory device includes a data traffic counter that retains a data traffic transferred in accordance with a reading command within a certain time period. Subsequently, the data transfer is prohibited when it is determined that the data is transferred from the memory device to the host device at a speed faster than a data transfer speed requisite at the time of playing of a motion image based on a value retained by the data traffic counter.
